View source for Docker: Save Current State

[[File:Docker Logo.png|center|frameless|250x250px]]

# Use <code>docker commit</code> to save a containers current state.
#* <code>docker commit nginx nginx:backup</code>
# This adds an image of the container to the local repository.  So, if a change is made to a container and needs to be reverted it can be done so individually.
# To remove an image use <code>docker images</code> to list all images and  <code>docker rmi</code> to remove the image by <code>name:tag</code> or Image ID.
#* <code>docker images</code>
#* <code>docker rmi nginx:backup</code>
